GW627368X is a potent and selective prostaglandin E2 receptor EP4 antagonist with additional affinity for thromboxane A2 receptor (pKi = 7.0/EP4, 6.8/TP, <5.3/DP, EP1, EP2, EP3, FP & IP) that effectively reduces basal (non-detectable at 0.1 nM with COX inhibition or pIC50 = 6.3 without) and PGE2-stimulated cAMP (pKb = 7.9) in human EP4-expressing HEK293 cells. GW627368X inhibits EP4-, but not EP2-, induced tissue relaxation (pKb = 9.2; precontracted piglet & rabbit saphenous vein), but not TP agonist U46619-elevated tissue tone (pKb <5) ex vivo, and blocks PGE2-enhanced HBV virus replication in mice in vivo (1 mg/kg/day i.p.) by preventing CD8 + T-cell impairment by PGE2
